Sealed bottle

Abstract

A blow molding apparatus including a pair of mold halves, a sealing blade mounted in one mold half and extendable into the mold cavity to seal the blown bottle, a drive member and an angled force multiplying drive connecting the drive member and blade is used in a method to produce a molded sealed bottle.

What we claim as our invention is: 
     
       1. A blow molded bottle comprising an integral body of thermoplastic resin, said body having a hollow interior surrounded by an imperforate wall and a seal neck having a longitudinal axis, said seal neck including a pair of spaced apart welded seals joining the plastic forming opposing sides of the seal neck, said seals being axially offset, each seal independently closing the interior of the body. 
     
     
       2. A bottle as in claim 1 wherein said seals are located at spaced locations along the length of the seal neck and are diagonally spaced apart across the seal neck. 
     
     
       3. A bottle as in claim 2 further including a third seal extending diagonally across the seal neck. 
     
     
       4. A bottle as in claim 2 wherein said seal neck includes a third independent seal. 
     
     
       5. A bottle as in claim 4 wherein said third seal is located between said pair of seals. 
     
     
       6. A bottle as in claim 1 wherein the interior of the bottle is sterile. 
     
     
       7. A bottle as in claim 1 including a gas within the hollow interior, said gas having a subatmospheric pressure. 
     
     
       8. A bottle as in claim 1 wherein said integral body includes a blow dome on the end of the seal neck away from the wall. 
     
     
       9. A blow molded bottle comprising an integral body of thermoplastic resin, said body having a hollow interior surrounded by an imperforate wall and a seal neck having a pair of spaced apart welded seals joining the plastic at opposite sides of the seal neck and located at spaced locations along the length of the seal neck, and a third seal located between said pair of seals, each seal independently closing the interior of the body. 
     
     
       10. A bottle as in claim 9 wherein said third seal extends diagonally across the width of the seal neck. 
     
     
       11. A bottle as in claim 9 wherein the interior of the bottle is sterile. 
     
     
       12. A bottle as in claim 11 including a gas within the hollow interior, said gas having a subatmospheric pressure. 
     
     
       13. A bottle as in claim 9 wherein said integral body includes a blow dome on the end of the seal neck away from the wall.
